Laptop schematic PDF labelled 4752 with the project code JE40 HR MB, where MB indicates the mainboard. The number 4752 likely refers to the notebook model, but no brand is stated, so confirm by matching JE40 HR markings on the PCB. The document lets a technician follow rails from the adapter input through the regulators, check the power sequence and locate components near a short. Any PDF viewer opens it; verify the board revision before using component values or connector pinouts.
